Arecibo: Google devotes doodle to mark the 44th anniversary of the Arecibo message



November 16, 2018 marks 44 years since researchers sent humanity's first interstellar radio message – a performance that Google celebrates with a daddy.

Forty-five years ago today, a group of researchers at the Arecibo Observatory gathered in the heart of Puerto Rico's tropical forests to try out humanity's first communication with intelligent life beyond our own planet.

Three-minute radio announcement, a series of exactly 1 679 binary numbers (one multiple of two prime numbers) that could be arranged in a raster of 73 rows of 23 columns – was directed to a cluster of stars 25,000 light years away from the ground.

Researchers sent the message via frequency modulated radio waves to a cluster of stars 25,000 light years away to demonstrate the power of the Arecibo radio telescope, which was the largest and most powerful in the world.

This historical transfer was designed to show the ability of Areciba's recently upgraded radio telescope, whose 1000-foot diameter dish made it the largest and most powerful in the world at the time.

"It was strictly a symbolic event to show that we could do it," said Donald Campbell, Cornell University professor of astronomy, who was a research assistant at the Arecibo Observatory at that time. Nevertheless, some of the present tears were moved.

The message itself was designed by a team of researchers from Cornell University, led by Dr Frank Drake, astronomer and astrophysicist, responsible for Drake Equation, a way to estimate the number of planets that hold alien life in Winter Street. & # 39; & # 39; What could we do that would be spectacular? & # 39; & # 39; Drake revoked thinking. "We could send a message!"

Written using Carl Sagan, the message itself can be arranged in a rectangular grid of 0s and 1s to form a pictogram representing some basic facts about mathematics, human DNA, the planet's soil in the solar system and an image of a human-like figure as well as a picture of the telescope itself.

Since the Arecibo message has been sent, the message has traveled only 259 trillion miles – a fraction of the trip to its intended destination, which takes about 25,000 years to complete.
